Abdominal ultrasound (complete) [HCPCS 76700]

A real time abdominal ultrasound is performed with image documentation. The patient is placed supine. Acoustic coupling gel is applied to the skin of the abdomen. The transducer is pressed firmly against the skin and swept back and forth over the abdomen and images obtained. The ultrasonic wave pulses directed at the abdomen are imaged by recording the ultrasound echoes. Any abnormalities are evaluated to identify characteristics that might provide a definitive diagnosis. The physician reviews the ultrasound images of the abdomen and provides a written interpretation.

Colon (large bowel) examination and biopsy with endoscope [HCPCS 45380]

A flexible colonoscopy is performed with single or multiple biopsies. The colonoscope is inserted into the rectum and advanced through the colon to the cecum or a point within the terminal ileum, using air insufflation to separate the mucosal folds for better visualization. Mucosal surfaces of the colon are inspected and any abnormalities are noted. The endoscope is then withdrawn and mucosal surfaces are again inspected for ulcerations, varices, bleeding sites, lesions, strictures, or other abnormalities. Any suspect site(s) to be biopsied is identified and biopsy forceps are placed through the biopsy channel in the endoscope. The forceps are opened, the tissue is spiked, and the forceps are closed. The biopsied tissue is then removed through the endoscope. One or more tissue samples may be obtained and are sent for separately reportable laboratory analysis.

Colon (large bowel) examination and polyps or tumors removal by snare technique with endoscope [HCPCS 45385]

A flexible colonoscopy is performed with removal of tumors, polyps, or other lesions by hot biopsy forceps or snare technique. The colonoscope is inserted into the rectum and advanced through the colon to the cecum or a point within the terminal ileum, using air insufflation to separate the mucosal folds for better visualization. Mucosal surfaces of the colon are inspected and any abnormalities are noted. The tumor, polyp, or other lesion is identified. Hot biopsy method uses insulated monopolar forceps to remove and electrocoagulate (cauterize) tissue simultaneously. Hot biopsy forceps are used primarily for removal of small polyps and treatment of vascular ectasias. A wire snare loop is placed around the lesion. The loop is heated to shave off and cauterize the lesion. Lesions may be removed en bloc with one placement of the snare or in a piecemeal fashion which requires multiple applications of the snare. The endoscope is withdrawn and mucosal surfaces are again inspected for ulcerations, bleeding sites, lesions, strictures, or other abnormalities.

Colon (large bowel) examination with endoscope for diagnosis (high risk) [HCPCS 45378]

A flexible colonoscopy is performed with or without collection of specimens by brushing or washing. The colonoscope is inserted into the rectum and advanced through the colon to the cecum or a point within the terminal ileum, using air insufflation to separate the mucosal folds for better visualization. Mucosal surfaces of the colon are inspected and any abnormalities are noted. The endoscope is then withdrawn as mucosal surfaces are again inspected for ulcerations, varices, bleeding sites, lesions, strictures, or other abnormalities. Cytology (cell) samples may be obtained using a brush introduced through the endoscope. Alternatively, sterile water may be introduced to wash the mucosal lining and the fluid aspirated to obtain cell samples. Cytology samples are sent for separately reportable laboratory analysis.

Imaging of leg joint by MRI without contrast [HCPCS 73721]

Magnetic resonance imaging is done on a joint of the upper or lower leg. Magnetic resonance is a noninvasive, non-radiating imaging technique that uses the magnetic properties of hydrogen atoms in the body. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. The powerful magnetic field forces the hydrogen atoms to line up. Radiowaves are then transmitted within the strong magnetic field. Protons in the nuclei of different types of tissues emit a specific radiofrequency signal that bounces back to the computer, which processes the signals and converts the data into tomographic, 3D images with very high resolution. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. Small coils that help transmit and receive the radiowaves may be placed around the joint. MRI scans on joints of the lower extremity are often done for injury, trauma, unexplained pain, redness, or swelling, and freezing of a joint with loss of motion. MRI scans provide clear images of areas that may be difficult to see on CT. The physician reviews the images to look for information that may correlate to the patient's signs or symptoms. MRI provides reliable information on the presence and extent of tumors, masses, or lesions within the joint; infection, inflammation, and swelling of soft tissue; muscle atrophy and other anomalous muscular development; and joint effusion and vascular necrosis.

Imaging of lower spinal canal by MRI without contrast [HCPCS 72148]

Magnetic resonance imaging (MRI) is done on the lumbar spinal canal and contents. MRI is a noninvasive, non-radiating imaging technique that uses the magnetic properties of nuclei within hydrogen atoms of the body. The powerful magnetic field forces the hydrogen atoms to line up. Radiowaves are then transmitted within the strong magnetic field. Protons in the nuclei of different types of tissues emit a specific radiofrequency signal that bounces back to the computer, which records the images. The computer processes the signals and coverts the data into tomographic, 3D, sectional images in slices with very high resolution. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. MRI scans of the spine are often done when conservative treatment of back pain is unsuccessful and more aggressive treatments are considered or following surgery. The physician reviews the images to look for specific information that may correlate to the patient's symptoms, such as abnormal spinal alignment; disease or injury of vertebral bodies; intervertebral disc herniation, degeneration, or dehydration; the size of the spinal canal to accommodate the cord and nerve roots; pinched or inflamed nerves; or any changes since surgery.

Imaging of pelvis by ultrasound through vagina [HCPCS 76830]

A transvaginal ultrasound is performed to evaluate the non-pregnant uterus and other pelvic structures. Conditions that may be evaluated by transvaginal ultrasound include infertility, abnormal bleeding, unexplained pain, congenital anomalies of the ovaries and uterus, ovarian cysts and tumors, pelvic inflammatory disease, bladder abnormalities, and intrauterine device (IUD) location. The patient is asked to empty the bladder and then lies back with the feet in stirrups. A protective cover is placed over the transducer and acoustic coupling gel is applied. The transducer is inserted into the vagina. Images of the uterus, ovaries, and surrounding pelvic structures are obtained from different orientations of the transducer. The ultrasonic wave pulses directed at the pelvic structures are imaged by recording the ultrasound echoes. The uterus is examined and endometrial thickness is determined. The ovaries are examined and any ovarian masses are carefully evaluated. The bladder and other pelvic structures are examined and any abnormalities are noted. The physician reviews the transvaginal ultrasound images and provides a written interpretation.

Lab analysis of urine specimen by dipstick with microscope (automated) [HCPCS 81001]

A urinalysis is performed by dip stick or tablet reagent for bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, and/or urobilinogen. Urinalysis can quickly screen for conditions that do not immediately produce symptoms such as diabetes mellitus, kidney disease, or urinary tract infection. A dip stick allows qualitative and semi-quantitative analysis using a paper or plastic stick with color strips for each agent being tested. The stick is dipped in the urine specimen and the color strips are then compared to a color chart to determine the presence or absence and/or a rough estimate of the concentration of each agent tested. Reagent tablets use an absorbent mat with a few drops of urine placed on the mat followed by a reagent tablet. A drop of distilled, deionized water is then placed on the tablet and the color change is observed. Bilirubin is a byproduct of the breakdown of red blood cells by the liver. Normally bilirubin is excreted through the bowel, but in patients with liver disease, bilirubin is filtered by the kidneys and excreted in the urine. Glucose is a sugar that is normally filtered by the glomerulus and excreted only in small quantities in the urine. Excess sugar in the urine (glycosuria) is indicative of diabetes mellitus. The peroxidase activity of erythrocytes is used to detect hemoglobin in the urine which may be indicative of hematuria, myoglobinuria, or hemoglobinuria. Ketones in the urine are the result of diabetic ketoacidosis or calorie deprivation (starvation). A leukocyte esterase test identifies the presence of white blood cells in the urine. The presence of nitrites in the urine is indicative of bacteria. The pH identifies the acid-base levels in the urine. The presence of excessive amounts of protein (proteinuria) may be indicative of nephrotic syndrome. Specific gravity measures urine density and is indicative of the kidneys' ability to concentrate and dilute urine. Following dip stick or reagent testing, the urine sample may be examined under a microscope. The urine sample is placed in a test tube and centrifuged. The sediment is resuspended. A drop of the resuspended sediment is then placed on a glass slide, cover-slipped, and examined under a microscope for crystals, casts, squamous cells, blood (white, red) cells, and bacteria.

Lab analysis to evaluate kidney function via a blood test panel [HCPCS 80069]

A renal panel is obtained for routine health screening and to monitor conditions such as diabetes, renal disease, liver disease, nutritional disorders, thyroid and parathyroid function, and interventional drug therapies. Tests in a renal panel include glucose or blood sugar; electrolytes and minerals as sodium, potassium, chloride, total calcium, and phosphorus; the waste products blood urea nitrogen (BUN) and creatinine; a protein called albumin; and bicarbonate (carbon dioxide, CO2) responsible for acid base balance. Glucose is the main source of energy for the body and is regulated by insulin. High levels may indicate diabetes or impaired kidney function. Sodium is found primarily outside cells and maintains water balance in the tissues, as well as nerve and muscle function. Potassium is primarily found inside cells and affects heart rhythm, cell metabolism, and muscle function. Chloride moves freely in and out of cells to regulate fluid levels and help maintain electrical neutrality. Calcium is needed to support metabolic processes, heart and nerve function, muscle contraction, and blood clotting. Phosphorus is essential for energy production, nerve and muscle function, and bone growth. Blood urea nitrogen (BUN) and creatinine are waste products from tissue breakdown that circulate in the blood and are filtered out by the kidneys. Albumin, a protein made by the liver, helps to nourish tissue and transport hormones, vitamins, drugs, and calcium throughout the body. Bicarbonate (HCO3) may also be referred to as carbon dioxide (CO2) maintains body pH or the acid/base balance. A specimen is obtained by separately reportable venipuncture. Serum/plasma is tested using quantitative chemiluminescent immunoassay or quantitative enzyme-linked immunosorbent assay.

Lab analysis to evaluate the clotting time in plasma specimen and monitor drug effectiveness [HCPCS 85610]

Prothrombin time (PT) measures how long it takes for blood to clot. Prothrombin, also called factor II, is one of the clotting factors made by the liver and adequate levels of vitamin K are needed for the liver to produce sufficient prothrombin. Prothrombin time is used to help identify the cause of abnormal bleeding or bruising; to check whether blood thinning medication, such as warfarin (Coumadin), is working; to check for low levels of blood clotting factors I, II, V, VII, and X; to check for low levels of vitamin K; to check liver function, to see how quickly the body is using up its clotting factors. The test is performed using electromagnetic mechanical clot detection. If prothrombin time is elevated and the patient is not on a blood thinning medication, a second prothrombin time using substitution plasma fractions, also referred to as a prothrombin time mixing study, may be performed. This is performed by mixing patient plasma with normal plasma using a 1:1 mix. The mixture is incubated and the clotting time is again measured. If the result does not correct, it may be indicative that the patient has an inhibitor, such as lupus anticoagulant. If the result does correct, the patient may have a coagulation factor deficiency.

Lab analysis to identify the thyroid stimulating hormone (tsh) in blood specimen [HCPCS 84443]

A blood test is performed to determine levels of thyroid stimulating hormone (TSH). TSH is produced in the pituitary and helps to regulate two other thyroid hormones, triiodothyronine (T3) and thyroxin (T4), which in turn help regulate the body's metabolic processes. TSH levels are tested to determine whether the thyroid is functioning properly. Patients with symptoms of weight gain, tiredness, dry skin, constipation, or menstrual irregularities may have an underactive thyroid (hypothyroidism). Patients with symptoms of weight loss, rapid heart rate, nervousness, diarrhea, feeling of being too hot, or menstrual irregularities may have an overactive thyroid (hypothyroidism). TSH levels are also periodically tested in individuals on thyroid medications. The test is performed by electrochemiluminescent immunoassay.

Lab analysis to measure coagulation in plasma or whole blood specimen [HCPCS 85730]

This test may also be referred to as an activated PTT or aPTT. PTT may be performed to diagnose the cause of bleeding or as a screening test prior to surgery to rule-out coagulation defects. A silica and synthetic phospholipid PTT reagent is mixed with the patient plasma. The silica provides a negatively-charged particulate surface that activates the contact pathway for coagulation. Clot formation is initiated by adding calcium chloride to the mixture. Clotting time is measured photo-optically.

Lab analysis to measure the amount of lipids (cholesterol and triglycerides) in blood specimen [HCPCS 80061]

"A lipid panel is obtained to assess the risk for cardiovascular disease and to monitor appropriate treatment. Lipids are comprised of cholesterol, protein, and triglycerides. They are stored in cells and circulate in the blood. Lipids are important for cell health and as an energy source. A lipid panel should include a measurement of triglycerides and total serum cholesterol and then calculate to find the measurement of high density lipoprotein (HDL-C), low density lipoprotein (LDL-C) and very low density lipoprotein (VLDL-C). HDL contains the highest ratio of cholesterol and is often referred to as ""good cholesterol"" because it is capable of transporting excess cholesterol in the blood to the liver for removal. LDL contains the highest ratio of protein and is considered ""bad cholesterol"" because it transports and deposits cholesterol in the walls of blood vessels. VLDL contains the highest ratio of triglycerides and high levels are also considered ""bad"" because it converts to LDL after depositing triglyceride molecules in the walls of blood vessels. A blood sample is obtained by separately reportable venipuncture or finger stick. Serum/plasma is tested using quantitative enzymatic method."

Lab analysis via blood test to measure a comprehensive group of blood chemicals [HCPCS 80053]

A comprehensive metabolic panel is obtained that includes albumin, bilirubin, total calcium, carbon dioxide, chloride, creatinine, glucose, alkaline phosphatase, potassium, total protein, sodium, alanine amino transferase (ALT) (SGPT), aspartate amino transferase (AST) (SGOT), and urea nitrogen (BUN). This test is used to evaluate electrolytes and fluid balance as well as liver and kidney function. It is also used to help rule out conditions such as diabetes. Tests related to electrolytes and fluid balance include: carbon dioxide, chloride, potassium, and sodium. Tests specific to liver function include: albumin, bilirubin, alkaline phosphatase, ALT, AST, and total protein. Tests specific to kidney function include: BUN and creatinine. Calcium is needed to support metabolic processes such as heart function, muscle contraction, nerve function, and blood clotting. Glucose is the main source of energy for the body and is regulated by insulin. Glucose measurement determines whether the glucose/insulin metabolic process is functioning properly.

Mammography of both breasts (screening exam) [HCPCS 77067]

Bilateral screening mammography is done with computer-aided lesion detection (CAD), when performed. Mammography is the radiographic imaging of the breast using low-dose ionizing radiation. The x-rays used in mammography have a longer wavelength than those typically used for bone imaging. A screening mammogram is done on asymptomatic women for early breast cancer detection when there are no known palpable masses. This is done on both breasts with two views taken on each side. The breast is compressed between planes on a machine dedicated strictly to mammography. This evens out the dense tissue and holds the breast still for a better quality image. Computer-aided detection uses algorithm analysis of the image data obtained from the mammographic films, with or without digitization of the radiographic images. The mammographic picture of the breast is used by scanning the x-ray film with a laser beam, usually converting the scanned image of the analog film into digital data for the computer first, then employing a methodical, step-by-step pattern of analyzing the data on video display for unusual or suspicious areas.

Mammography of both breasts for diagnosis [HCPCS 77066]

These codes report diagnostic mammography of one breast or both breasts with computer-aided lesion detection (CAD), when performed. Mammography is the radiographic imaging of the breast using low-dose ionizing radiation. The x-rays used in mammography have a longer wavelength that those typically used for bone imaging. The test is done to detect tumors or cysts in women who have symptoms of breast disease or a palpable mass. The breast is compressed between planes on a machine dedicated strictly to mammography. This evens out the dense tissue and holds the breast still for a better quality image. Computer-aided detection uses algorithm analysis of the image data obtained from the mammographic films, with or without digitization of the radiographic images.

Spinal x-ray of lower and sacral spine (minimum of 4 views) [HCPCS 72110]

A radiologic exam is done of the lumbosacral spine. Frontal, posteroanterior, and lateral views are the most common projections taken. X-ray uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures.

Lab analysis by immunoassay (ELISA) to identify Influenza virus (A or B) [HCPCS 87400]

Lab analysis by nucleic acid (DNA or RNA) to identify chlamydia trachomatis by amplified probe technique [HCPCS 87491]

Infectious agent antibody detection by nucleic acid technique (DNA or RNA) is used to identify Chlamydia trachomatis infection using direct probe, amplified probe, or quantification of the amplified probe. C. trachomatis infection is a sexually transmitted disease (STD) that often produces no symptoms, but can cause irreversible damage to the female reproductive tract, resulting in infertility. In men, symptoms include burning and itching of the urethra, but men rarely suffer reproductive damage from the infection. Some types of nucleic acid tests are rapid tests that may be performed in the physician office using a test kit. A swab is used to obtain a specimen from the cervix, male urethra, or eye. The exact methodology is dependent on the test kit used as there are several manufacturers. One test kit uses a nucleic acid hybridization method. A single stranded chemiluminescent DNA probe is used that is complementary to the ribosomal RNA of the Chlamydia organism. Lysate is used to rupture cells and release nucleic acids. The ribosomal RNA from the Chlamydia organism then combines with the labeled DNA probe to form a stable DNA:RNA hybrid. The presence of DNA:RNA hybrids is then detected using a luminometer. In an amplification technique, such as polymerase chain reaction (PCR), is used to create copies of the Chlamydia nucleic acids. Amplification is used when it is suspected that there are low levels of the targeted microorganism in the specimen that would not be detected using a direct probe. The Chlamydia nucleic acid is then detected using a variety of techniques.

Lab analysis by nucleic acid (DNA or RNA) to identify clostridium difficile by amplified probe technique [HCPCS 87493]

Lab analysis by nucleic acid (DNA or RNA) to identify Neisseria gonorrhoeae (gonorrhoeae bacteria) by amplified probe technique [HCPCS 87591]

Neisseria gonorrhoeae (N. gonorrhoeae) causes gonorrhea, a sexually transmitted disease (STD), that is spread through direct contact and can infect the reproductive tract, mouth, throat, eyes, and anus. N. gonorrhoeae often causes no symptoms in women, but can cause irreversible damage to the reproductive tract of women which can result in infertility. In men, symptoms include burning, itching, and discharge of the urethra, but men rarely suffer reproductive damage from the infection. Some types of nucleic acid tests are rapid tests that may be performed in the physician office using a test kit. A swab is used to obtain a specimen from the cervix, male urethra, mouth, throat, or eye. An amplification technique, such as polymerase chain reaction (PCR) or transcription mediated amplification (TMA) is used to create copies of the N. gonorrhoeae nucleic acids. Amplification is used when there may be low levels of the suspected microorganism in the specimen that would not be detected using a direct probe. The N. gonorrhoeae nucleic acid is then detected using a variety of techniques.

Lab analysis to evaluate thyroid hormone in serum specimen [HCPCS 84479]

Lab analysis to identify total thyroxine (thyroid chemical) function in serum specimen for screening [HCPCS 84436]

A blood sample is obtained and levels of total thyroxin (84436), thyroxine requiring elution as for testing in neonates (84437), or free thyroxine (84439) are evaluated. Thyroxine, also referred to as T4, is tested to determine whether the thyroid is functioning properly and is used to aid in the diagnosis of overactive (hyperthyroidism) or underactive (hypothyroidism) thyroid function. In 84436, total thyroxine levels are evaluated. Total thyroxine measures the total amount of both bound and unbound (free) thyroxine in the blood. All thyroxine tests use electrochemiluminescent immunoassay methodology. *

Lab analysis to measure blood count (hemoglobin) [HCPCS 85018]

A blood test is performed to determine hemoglobin (Hgb) which is a measurement of the amount of oxygen-carrying protein in the blood. Hgb is measured to determine the severity of anemia or polycythemia, monitor response to treatment for these conditions, or determine the need for blood transfusion. A blood sample is collected by separately reportable venipuncture or finger, heel, or ear stick. The sample may be sent to the lab or a rapid testing system may be used in the physician's office. Systems consist of a portable photometer and pipettes that contain reagent. The pipette is used to collect the blood sample from a capillary stick and the blood is automatically mixed with the reagent in the pipette. The photometer is then used to read the result which is displayed on the photometer device.

Lab analysis to measure blood glucose (sugar) level with hand-held instrument [HCPCS 82962]

A portable testing device called a glucometer is used at the patient's home or a physician's office to monitor glucose levels in the the blood. Glucose is a monosaccharide (single sugar) used for energy by the body. Certain diseases, such as diabetes, and medications may cause glucose levels to be abnormally high or low. A blood sample is obtained by fingerstick and placed on a test strip. Most commercial glucometers use a chemically treated test strip that produces a small electric current when blood is introduced. The strength of the electrical charge is dependent on the level of glucose in the sample. The glucose level is displayed on the monitoring device in a numeric measurement as mg/dL. This code is only reported when the physician or other healthcare professional uses this type of device in the office or other setting to check glucose levels, not when the patient self-administers the test.

Lab analysis to measure coagulation function measurement of D-dimer (quantitative) [HCPCS 85379]

D-dimer testing for fibrin degradation products is performed to help rule out the presence of a thrombus. D-dimer tests are also used to rule-out hypercoagulability. D-dimer has a negative predictive value for these conditions which means that a negative result indicates that there is not an elevated level of fibrin degradation products present in the specimen. A positive result indicates an abnormally high level of fibrin degradation products which may be indicative of a thrombus. It is used to help diagnosis deep vein thrombophlebitis, pulmonary embolus, and stroke. The test is also used to evaluate for hypercoagulability which predisposes the patient to blood clots and to help diagnose disseminated intravascular coagulation (DIC) and monitor the effectiveness of DIC treatment.

Lab analysis to measure free thyroxine (thyroid chemical) in serum specimen [HCPCS 84439]

A blood sample is obtained and levels of total thyroxin, thyroxine requiring elution as for testing in neonates or free thyroxine are evaluated. Thyroxine, also referred to as T4, is tested to determine whether the thyroid is functioning properly and is used to aid in the diagnosis of overactive (hyperthyroidism) or underactive (hypothyroidism) thyroid function. In free thyroxine levels are tested. Free thyroxine is the amount of active thyroxine in the blood. Free thyroxine levels are considered to be a more accurate indicator of thyroid function. All thyroxine tests use electrochemiluminescent immunoassay methodology.

Lab analysis to measure red blood cell concentration [HCPCS 85014]

A blood test is performed to determine hematocrit (Hct). Hematocrit refers to the volume of red blood cells (erythrocytes) in a given volume of blood and is usually expressed as a percentage of total blood volume. A blood sample is obtained by separately reportable venipuncture or finger, heel, or ear stick. Hct is calculated using an electronic cell counter.

Lab analysis to measure red blood cell sedimentation rate to detect inflammation (non-automated) [HCPCS 85651]

Lab test for Sedimentation rate

Lab analysis to measure the ammonia level [HCPCS 82140]

A blood test is performed to measure ammonia levels. Ammonia is a by product of protein metabolism and is normally converted to urea by the liver and excreted via the kidney. Elevated ammonia levels may result from cirrhosis or hepatitis. Symptoms of elevated ammonia levels are confusion, tremors, excessive sleepiness, or coma. Testing may be performed in disease states such as Reyes syndrome or liver failure. A blood sample is obtained by a separately reportable venipuncture or arterial access line. The specimen is then tested using colorimetry.

Lab analysis to measure the amount of blood gases [HCPCS 82803]

A laboratory test is performed to measure one or more components of blood gases. The homeostatic acid-base balance is measured as blood pHùthe number of hydrogen ions (H+) dissolved in the blood. Partial pressure of carbon dioxide (pCO2) is the amount of carbon dioxide dissolved in the blood and reflects how well the lungs can move CO2 out of the body. Partial pressure of oxygen (pO2) is the level of oxygen dissolved in the blood and reflects the exchange of oxygen molecules in the alveoli. Bicarbonate (HCO3) is calculated from pH and pCO2 and is the metabolic component of acid-base balance reflecting the kidney's response to changes in pH. Oxygen saturation (O2 Sat) is the percent of hemoglobin that is carrying oxygen. Calculated O2 saturation uses a mathematical model to determine the percentage of hemoglobin that is carrying oxygen based on the level of pO2. Blood gas monitoring may be performed to evaluate lung function; detect an acid-base imbalance; monitor metabolic, respiratory, and kidney disorders; and evaluate the effectiveness of treatment. A blood sample is obtained by separately reportable venipuncture, heelstick, arterial, or umbilical cord draw.

Lab analysis to measure the amount of carbamazepine (total) in blood specimen [HCPCS 80156]

A laboratory test is performed to determine total or free carbamazepine levels. Carbamazepine, also referred to as Tegretol, is an anticonvulsant used to treat epilepsy and may also be used as an analgesic to treat trigeminal neuralgia. Carbamazepine, carbamazepine metabolite (10,11-epoxide), and free carbamazepine are routinely measured to determine optimal doses in patients with epilepsy as well as to monitor for carbamazepine toxicity. A blood sample is obtained by separately reportable venipuncture. Blood serum is then tested using one of several techniques including high performance liquid chromatography or fluorescent polarization immunoassay. Total carbamazepine tests the total amount present in the blood. Under normal circumstances, circulating carbamazepine is 75% protein bound. In some patients carbamazepine may be displaced from protein resulting in higher levels of free carbamazepine circulating in the blood. In these patients, lower levels of the drug may result in toxicity, so the unbound (free) levels must be monitored.

Lab analysis to measure the amount of C-reactive protein in serum to identify infection or inflammation [HCPCS 86140]

A blood test is performed to measure C-reactive protein (CRP) levels. This standard test has a wide value range. CRP is an acute phase protein, synthesized by the liver and released in response to inflammation and infection. The test is not diagnostic for any specific disease or condition but can be used as a marker to monitor the body's response to treatment(s) or to evaluate the need for further testing. Elevation of CRP levels may be found during pregnancy, with the use of oral contraceptives, or hormone replacement therapy. Diseases/conditions that cause an elevation of CRP include: lymphoma, arteritis/vasculitis, osteomyelitis, inflammatory bowel disease, rheumatoid arthritis, pelvic inflammatory disease (PID), systemic lupus erythematosus (SLE), acute infections, burns, surgical procedures, and organ transplants. A blood sample is obtained by separately reportable venipuncture. Serum in neonates is tested using immunoassay. Serum/plasma in all other patients is tested using quantitative immunoturbidimetric method.

Lab analysis to measure the amount of immune system protein (complement) antigens (each component) [HCPCS 86160]

A blood test is performed to measure complement antigen levels. Complement factors help to clear immune complexes from the blood. Proteins are activated in response to the immune complex and generate peptides that bind the complexes and complement receptors. The cell membrane breaks apart and an attack complex is formed. A blood sample is obtained by separately reportable venipuncture. Complements are tested in serum or plasma samples, using specified methods, particularly quantitative radial immunodiffusion. Report for each complement component tested: 2-9 (2 being the most common inherited complement deficiency), 3A (the most abundant of all complement components), 4A, and 1Q; complement factor B and Bb; and C1-esterase inhibitor.

Lab analysis to measure the amount of microsomal antibodies (autoantibody) [HCPCS 86376]

A blood test is performed to identify the presence of microsomal antibodies (thyroid or liver-kidney). Microsomes are located inside of cells in the thyroid, liver, and kidney. When these cells are damaged, microsomes are released, and the body produces antibodies to the microsomes in response to the damage. A blood sample is obtained by separately reportable venipuncture and tested for the presence of the microsomal antibodies. For the thyroid, the test is done to confirm thyroid problems, such as Hashimoto's thyroiditis, cancer, or nontoxic nodular goiter. For liver-kidney microsome antibody, semiquantitative indirect fluorescence or semiquantitative enzyme-linked immunosorbent assay is done to determine cell damage, such as with autoimmune hepatitis type 2 (AIH-2).

Lab analysis to measure the amount of total phenytoin in blood specimen [HCPCS 80185]

A blood test is performed to measure phenytoin total and phenytoin free levels. Phenytoin also known as Dilantin, Phenytek or Prompt, is an anticonvulsant prescribed to treat seizures and works by deceasing electrical activity in the brain. The drug may be administered orally or by injection. Phenytoin has a narrow therapeutic range and the patient should be monitored for both total and free phenytoin levels. Total phenytoin reflects the total serum concentration of the drug while free phenytoin levels reflect the unbound levels. Only the unbound levels are biologically active. Ninety (90) percent of the drug is typically highly bound and biologically inactive, but bound phenytoin is sensitive to displacement by other protein binding drugs which can elevate levels of free phenytoin in the blood. Blood concentration levels are monitored at regular intervals and also when breakthrough seizures occur, indicating possible low therapeutic levels. A blood sample is obtained by a separately reportable venipuncture. Blood serum is then tested using immunoassay.

Lab analysis to measure the amount of total valproic acid in blood specimen [HCPCS 80164]

A laboratory test is performed to measure valproic acid (dipropylacetic acid, depakote). Valproic acid is an anticonvulsant that may be used to treat seizure disorders, manic phase of bipolar disorders, and migraine headaches. The drug works by changing certain chemicals neurotransmitters in the brain. The test for total valproic acid can be used to monitor drug therapy, assess patient compliance, and evaluate for potential toxicity. The test for free valproic acid may be used to evaluate the cause of toxicity when the total valproic acid concentration is within the normal range. Free valproic acid may be elevated in patients with an altered or unpredictable protein binding capacity. A blood sample is obtained by separately reportable venipuncture just prior to medication administration to obtain the trough level. Serum/plasma is tested for total valproic acid using fluorescence polarization immunoassay and for free valproic acid using quantitative enzyme multiplied immunoassay.

Lab analysis to measure the amount of troponin (protein) in serum specimen [HCPCS 84484]

A blood test is performed to measure troponin levels. Troponins are regulatory proteins that facilitate contraction of skeletal and smooth muscle by forming calcium bonds. Troponin T binds to tropomyosin to form a complex. Troponin I binds to actin and holds the Troponin T-tropomyosin complex together. Elevation of troponins, coupled with cardiac symptoms such as chest pain are considered diagnostic for cardiac injury. This test is commonly ordered in the Emergency Department when a patient presents with possible myocardial infarction, and is then repeated at 6 hour intervals. It may be ordered with other tests that assess cardiac biomarkers such as CK, CK-MB, and myoglobin. A blood sample is obtained by separately reportable venipuncture. Serum/plasma is tested for Troponin T using quantitative electrochemiluminescent immunoassay. Serum is tested for Troponin I using chemiluminescent immunoassay.

Lab analysis to measure the blood potassium level in blood specimen [HCPCS 84132]

A blood sample is obtained to measure potassium level. Potassium is a positively charged electrolyte that works in conjunction with other electrolytes, such as sodium, chloride, and carbon dioxide (CO2), to regulate body fluid, stimulate muscle contraction, and maintain proper acid-base balance. Potassium is found in all body fluids but mostly stored within cells, not in extracellular fluids, blood serum, or plasma. Small fluctuations in blood potassium, either too high (hyperkalemia) or too low (hypokalemia), can have serious, even life-threatening, consequences. Potassium level is used to screen for and monitor renal disease; monitor patients on certain medications, such as diuretics, as well as patients with acute and chronic conditions, such as dehydration or endocrine disorders. Because blood potassium affects heart rhythm and respiratory rate, it is routinely checked prior to major surgical procedures. Potassium is measured by ion-selective electrode (ISE) methodology.

Lab analysis to measure the c-peptide (protein) level in urine specimen [HCPCS 84681]

Lab analysis to measure the creatine kinase (cardiac enzyme) level (MB fraction only) [HCPCS 82553]

Creatine kinase (CK) also known as, creatine phosphokinase (CPK), is an enzyme found in the heart, brain, skeletal muscle and certain other tissue. The subtypes are known as CK-MM found primarily in skeletal and heart muscle, CK-MB found in heart muscle and CK-BB located in the brain. CK circulating in blood rarely contains CK-BB but is largely comprised of CK-MM or CK-MB. Levels may be elevated following heart muscle damage (heart attack/myocardial infarction) and skeletal muscle injury (trauma, vigorous exercise). Statin drugs that lower cholesterol level and alcohol intake may cause elevated CK blood levels. Only creatine kinase (CK) MB fraction is measured. Testing for this isoenzyme can help identify heart muscle damage following a heart attack (myocardial infarction). A blood test is obtained by separately reportable venipuncture. Serum is tested using chemiluminescent immunoassay.

Lab analysis to measure the creatinine level to test for kidney function or muscle injury (other than blood specimen) [HCPCS 82570]

A sample other than blood is taken to measure creatinine levels. Creatinine is a waste product produced by the muscles in the breakdown of creatine, which is a compound used by the muscles to create energy for contraction. The waste product, creatinine, is excreted by the kidneys and blood levels provide a good measurement of renal function. Creatinine may be checked to screen for or monitor treatment of renal disease. Creatinine levels may also be monitored in patients with acute or chronic illnesses that may impair renal function and in patients on medications that affect renal function. Creatinine clearance, also known as urea or urea nitrogen clearance tests both blood and urine samples for a calculation of creatinine content adjusted for urine volume and physical size as a general indicator of glomerular filtration function.

Lab analysis to measure the cyanocobalamin (vitamin b-12) level [HCPCS 82607]

Cyanocobalamin is a vitamer of the B-12 vitamin family and plays an important role in metabolism, red blood cell production and nervous system function. Blood levels of cyanocobalamin are measured. Blood levels may be reduced with pernicious and other forms of anemia, and in individuals who follow a strict vegan diet, have chronic infections (such as HIV) and during pregnancy. A blood sample is obtained by separately reportable venipuncture. Serum is tested using quantitative chemiluminescent immunoassay.

Lab analysis to measure the ferritin (blood protein) level [HCPCS 82728]

A blood test is performed to measure ferritin levels. Ferritin is an intracellular protein that stores iron and releases it into circulation in a controlled manner to protect the body against iron overload and iron deficiency. Ferritin levels may be obtained to evaluate for elevated levels caused by excess storage diseases such as hemochromatosis and following multiple transfusions. Levels may also be obtained to evaluate for decreased levels due to iron deficiency. A blood sample is obtained by separately reportable venipuncture. Serum is tested using quantitative chemiluminescent immunoassay.

Lab analysis to measure the folic acid level in serum specimen [HCPCS 82746]

A blood test is performed to measure folic acid (folate) levels in serum or red blood cells (RBC). Folic acid (folate) may also be referred to as Vitamin B9 and is essential for the growth, division and repair of cells, especially fetal growth during pregnancy and in early infancy. It is also necessary for the production of healthy red blood cells and to prevent anemia at all ages. The test may be used to diagnose anemia or certain neuropathies and to monitor the effectiveness of treatment for these conditions. A blood sample is obtained by separately reportable venipuncture.

Lab analysis to measure the glucose (sugar) level in blood [HCPCS 82947]

A blood sample is obtained to measure total (quantitative) blood glucose level. Glucose is a simple sugar that is the main source of energy for the body. Carbohydrates are broken down into simple sugars, primarily glucose, absorbed by the intestine, and circulated in the blood. Insulin, a hormone produced by the pancreas, regulates glucose level in the blood and transports glucose to cells in other tissues and organs. When more glucose is available in the blood than is required, it is converted to glycogen and stored in the liver or converted to fat and stored in adipose (fat) tissue. If the glucose/insulin metabolic process is working properly, blood glucose will remain at a fairly constant, healthy level. Glucose is measured to determine whether the glucose/insulin metabolic process is functioning properly. It is used to monitor glucose levels and determine whether they are too low (hypoglycemia) or too high (hyperglycemia) as well as test for diabetes and monitor blood sugar control in diabetics.

Lab analysis to measure the hemoglobin A1C level in blood specimen [HCPCS 83036]

A blood test is performed to measure glycosylated hemoglobin (HbA1C) levels. Plasma glucose binds to hemoglobin and the HbA1C test measures the average plasma glucose concentration over the life of red blood cells (approximately 90-120 days). HbA1C levels may be used as a diagnostic reference for patients with suspected diabetes mellitus (DM) and to monitor blood glucose control in patients with known DM. HbA1C levels should be monitored at least every 6 months in patients with DM and more frequently when the level is >7.0%. A blood sample is obtained by separately reportable venipuncture. Whole blood is tested using quantitative high performance liquid chromatography/boronate affinity.

Lab analysis to measure the iron binding capacity [HCPCS 83550]

A blood test is performed to measure the iron binding capacity of transferrin. Transferrin, a protein found in circulating blood is responsible for carrying iron molecules. This test measures the ability of transferrin to carry iron. A blood sample is obtained by separately reportable venipuncture. Serum or plasma is tested using quantitative spectrophotometry/calculation.

Lab analysis to measure the iron level [HCPCS 83540]

A blood, urine or liver test is performed to measure iron levels. Iron (Fe) is an essential element that circulates in the blood attached to the protein transferrin. Iron is necessary component of hemoglobin, found in red blood cells (RBCs) and myoglobin found in muscle cells. Low iron levels may cause a decrease in red blood cells and iron deficiency anemia. High iron levels may be caused by excessive intake of iron supplements or a hereditary genetic condition such as hemochromatosis from a mutation of the RGMc gene or HAMP gene. A blood sample is obtained by separately reportable venipuncture. Serum or plasma is tested using quantitative spectrophotometry. A random voided or 24 hour urine specimen is obtained and tested using quantitative inductively coupled plasma/emission spectrometry. Patient should wait 2-4 days after receiving iodine or gadolinium contrast media to collect a urine specimen. A liver sample is obtained by a separately reportable procedure. Liver tissue is tested using quantitative inductively coupled plasma-mass spectrometry.

Lab analysis to measure the lipase (fat enzyme) level [HCPCS 83690]

A test is performed on blood and body fluids to measure lipase levels. Lipase is an enzyme released by the pancreas into the small intestine and is essential for the digestion of dietary fats. Elevated levels may result from small bowel obstruction, celiac disease, cholecystitis, duodenal ulcer, severe gastroenteritis, macrolipasemia, pancreatitis, and pancreatic tumors. The test may be ordered when there is a family history of lipoprotein lipase deficiency. A blood sample is obtained by separately reportable venipuncture. Other body fluids collected by other methods. Blood and other body fluids are tested using quantitative enzymatic methodology.

Lab analysis to measure the magnesium level in body fluids and cells [HCPCS 83735]

A blood, urine, or fecal test is performed to measure magnesium levels. Magnesium is an essential dietary mineral responsible for enzyme function, energy production, and contraction and relaxation of muscle fibers. Decreased levels may result from severe burns, metabolic disorders, certain medications, and low blood calcium levels. A blood sample is obtained by separately reportable venipuncture. Red blood cells (RBCs) are tested using quantitative inductively coupled plasma-mass spectrometry. Serum/plasma is tested using quantitative spectrophotometry. A 24-hour voided urine specimen is tested using quantitative spectrophotometry. A random or 24-hour fecal sample is tested using quantitative spectrophotometry.

Lab analysis to measure the microalbumin (protein) level in urine specimen [HCPCS 82043]

A test on urine is used to measure microalbumin levels and is routinely performed annually on diabetic patients with stable blood glucose levels to assess for early onset nephropathy. The quantitative test, which measures the actual amount of microalbumin present in the urine, may be performed on a random urine sample, with a notation of total volume and voiding time, or a 24-hour urine sample using immunoturbidimetric technique. The semi-quantitative test identifies the presence of elevated microalbumin levels in the urine within a general range and involves a chemical dipstick placed into the urine sample which reacts and changes color when albumin is present.

Lab analysis to measure the natriuretic peptide (heart and blood vessel protein) level in plasma specimen [HCPCS 83880]

The level of the natriuretic peptide in the blood is measured to evaluate heart failure and to differentiate symptoms that might be indicative of heart failure from other disorders that cause similar symptoms. A separately reportable venipuncture is performed and whole blood or plasma collected using EDTA as an anticoagulant. An automated immunoassay is performed using murine monoclonal and polyclonal antibodies against natriuretic peptide. The antibodies are labeled with a fluorescent dye and immobilized on the solid phase. The specimen is placed in the sample chamber and the analysis is run. The physician reviews the results and uses them to make diagnosis and treatment decisions.

Lab analysis to measure the parathormone (parathyroid hormone) level [HCPCS 83970]

A blood or tissue test is performed to measure parathormone (parathyroid hormone, parathyrin) levels. Parathyroid hormone (PTH) is produced by chief cells in the parathyroid gland. The hormone helps to regulate blood calcium levels, absorption/excretion of phosphate by the kidneys and in Vitamin D synthesis in the body. Elevated levels (hyperparathyroidism) may be caused by parathyroid gland tumors or chronic renal failure. Decreased levels (hypoparathyroidism) may result from inadvertent removal (during thyroid gland surgery), autoimmune disorders or genetic inborn errors of metabolism. A blood sample is obtained by separately reportable venipuncture. Parathyroid gland tissue is obtained by separately reportable fine needle aspirate. Serum/plasma or tissue sample are tested using quantitative electrochemiluminescent immunoassay. Plasma is tested for parathyroid hormone, CAP (Cyclase Activating Parathyroid Hormone) using immunoradiometric assay.

Lab analysis to measure the phosphate level [HCPCS 84100]

A blood or urine test is performed to measure inorganic phosphorus (phosphate) levels. Phosphate is an intracellular anion, found primarily in bone and soft tissue.

Decreased levels are most often caused by malnutrition and lead to muscle and neurological dysfunction. Elevated levels may be due to kidney or parathyroid gland problems. A blood sample is obtained by separately reportable venipuncture. Serum/plasma is tested using quantitative spectrophotometry.

Lab analysis to measure the total calcium level in blood specimen [HCPCS 82310]

A blood sample is taken to measure the amount of total calcium. Calcium is one of the most important minerals in the body. About 99 percent of the calcium found the body is stored in the bones. The remaining one percent circulates in the blood. Calcium may be ionized (free) or attached (bound) to proteins. Free calcium is the calcium metabolically active in the body. Bound calcium is inactive. Total calcium is a measurement of the total amount of both free calcium and bound calcium circulating in the blood. Total calcium is measured to screen for or monitor a number of conditions, including those affecting the bones, heart, nerves, kidneys and teeth. Total calcium is measured using spectrophotometry.

Lab analysis to measure the total creatine kinase (cardiac enzyme) level in blood specimen [HCPCS 82550]

Creatine kinase (CK) also known as, creatine phosphokinase (CPK), is an enzyme found in the heart, brain, skeletal muscle and certain other tissue. The subtypes are known as CK-MM found primarily in skeletal and heart muscle, CK-MB found in heart muscle and CK-BB located in the brain. CK circulating in blood rarely contains CK-BB but is largely comprised of CK-MM or CK-MB. Levels may be elevated following heart muscle damage (heart attack/myocardial infarction) and skeletal muscle injury (trauma, vigorous exercise). Statin drugs that lower cholesterol level and alcohol intake may cause elevated CK blood levels. A blood test is performed to measure total creatine kinase (CK) levels. A blood specimen is obtained by separately reportable venipuncture. Serum or plasma is tested using quantitative enzymatic methodology.

Lab analysis to measure the total protein level in urine specimen [HCPCS 84156]

Lab analysis to measure the uric acid level in blood specimen [HCPCS 84550]

A blood test is performed to measure uric acid levels. Uric acid forms from the natural breakdown of body cells and the food we ingest. Uric acid is normally filtered by the kidneys and excreted in urine. Elevated blood levels may result from kidney disease, certain cancers and/or cancer therapies, hemolytic or sickle cell anemia, heart failure, cirrhosis, lead poisoning, and low levels of thyroid or parathyroid hormones. Levels may be decreased in Wilson's disease, poor dietary intake of protein, and with the use of certain drugs. A blood sample is obtained by separately reportable venipuncture. Serum/plasma is tested using quantitative spectrophotometry.

Lab analysis to measure the vitamin D-3 level in serum or plasma specimen [HCPCS 82306]

Blood levels of 25-hydroxyvitamin D are used to primarily to determine whether a deficiency of Vitamin D or abnormal metabolism of calcium is the cause of bone weakness or malformation. Vitamin D is a fat soluble vitamin that is absorbed from the intestine like fat, and 25-hydroxyvitamin D levels are also evaluated in individuals with conditions or diseases that interfere with fat absorption, such as cystic fibrosis, Crohn's disease, or in patients who have undergone gastric bypass surgery. A blood sample is obtained. Levels of 25-hydroxyvitamin D3 and 25-hydroxyvitamin D2 are evaluated using chemiluminescent immunoassay. The test results may be the sum of Vitamin D3 and D2 or the results may include fractions of D3 and D2 as well as the sum of these values.

Lab analysis to measure total testosterone (hormone) level in serum specimen [HCPCS 84403]

A urine test is performed to measure total testosterone level. Testosterone is an androgen hormone secreted in the testes of men, ovaries of women, and the adrenal glands of both sexes. Testosterone helps promote protein synthesis and supports the growth of cells and tissue. This test is often performed in conjunction with sex hormone binding globulin. A blood sample is obtained by separately reportable venipuncture. Serum/plasma of adult males is tested using quantitative electrochemiluminescent immunoassay with the value derived from a mathematical expression using sex hormone binding globulin (SHBG). Serum/plasma of adult males may also be tested using quantitative equilibrium dialysis/high performance liquid chromatography-tandem mass spectrometry. Serum/plasma of children and adult females is tested using quantitative high performance liquid chromatography-tandem mass spectrometry/electrochemiluminescent immunoassay with the value also derived from a mathematical expression using sex hormone binding globulin (SHBG).

Lab blood analysis to identify antigens on red blood cell surface and determine the patient's Rh (D) type (Rh positive or Rh negative) [HCPCS 86901]

A blood specimen is tested to determine blood type (ABO) or Rh(D). In Rh(D), blood is tested for Rh factor, which is an antigen on red blood cells. Blood is Rh+ if the antigen is present or Rh- if the antigen is absent. Blood is tested by mixing the blood sample with antibodies against Rh factor and then checking for agglutination. If agglutination occurs, the blood is Rh+. If the blood does not agglutinate, it is Rh-.

Function improvement activities with one-on-one contact between patient and provider (each 15 minutes) [HCPCS 97530]

In a one-on-one physical therapy session, the provider instructs and assists the patient in therapeutic activities designed to address specific functional limitations. The therapeutic activities are specifically developed and modified for the patient. Dynamic/movement activities, also called kinetic activities, that are designed to improve functional performance such as lifting, bending, pushing, pulling, jumping and reaching are included in this service. For example, the patient may be given therapeutic activities to perform to improve the ability to sit, stand, and get out of bed after an injury without straining or risking reinjury. This code is reported for each 15 minutes of one-on-one therapeutic activity provided.

Physcial therapy exercise of walking training to 1 or more areas (each 15 minutes) [HCPCS 97116]

Gait training is a therapeutic procedure that observes and educates an individual in the manner of walking including the rhythm, cadence, step, stride, and speed. The objective of gait training is to strengthen muscles and joints, improve balance and posture, and develop muscle memory. As the lower extremities are retrained for repetitive motion, the body also benefits from the exercise with increased endurance, improved heart/lung function, and reduced or improved osteoporosis. Gait training is an appropriate therapeutic procedure following brain and/or spinal cord injury, stroke, fracture of the pelvis and/or lower extremity, joint injury or replacement of the knee, hip, or ankle, amputation, and for certain musculoskeletal and/or neurological diseases. A treadmill fitted with a safety harness is initially used to ensure safe walking. As the patient gains strength and balance, step training and stair climbing is added to the treatment modality.

Physical therapy evaluation (typically 20 minutes) [HCPCS 97161]

A physical therapy evaluation or re-evaluation is performed. The physical therapist takes a history of the current complaint including onset of symptoms, comorbidities, changes since the onset, treatment received for the symptoms or condition, medications prescribed for it, and any other medications the patient is taking. A physical examination of body systems is done to assess physical structure and function, any activities or movements that exacerbate the symptoms, limit activity, or restrict participation in movement, as well as anything that helps to relieve the symptoms. The evaluation may involve provocative maneuvers or positions that increase symptoms; tests for joint flexibility and muscle strength; assessments of general mobility, posture, and core strength; evaluation of muscle tone; and tests for restrictions of movement caused by myofascial disorders. Following the history and physical, the therapist determines the patient's clinical presentation characteristics, provides a detailed explanation of the condition, identifies physical therapy treatment options, and explains how often and how long physical therapy modalities should be applied. The physical therapist will then develop a plan of care with clinical decision making based on patient assessment and/or measurable functional outcome. The plan of care may include both physical therapy in the clinic and exercises or changes in the home environment. Upon re-evaluation, the established care plan is reviewed and an interim history is taken requiring the use of standardized tests and measures. The patient's response to treatment is evaluated and the plan of care is revised based on the patient's measurable response.

The patient's response to treatment is evaluated and the plan of care is revised based on the patient's measurable response.

Physical therapy procedure to re-educate brain-to-nerve-to-muscle function (each 15 minutes) [HCPCS 97112]

Therapeutic procedures for neuromuscular reeducation are used to develop conscious control of a single muscle or muscle group and heighten the awareness of the body's position in space, especially the position of the extremities when sitting or standing. Neuromuscular reeducation is employed during the recovery or regeneration stage following severe injury or trauma, cerebral vascular accident, or systemic neurological disease. The goal of therapy is improved range of motion (ROM), balance, coordination, posture, and spatial awareness. Techniques may include proprioceptive neuromuscular facilitation which uses diagonal contract-relax patterns of skeletal muscles to stimulate receptors in the joints that communicate body position to the brain via motor and sensory nerves. Feldenkrais is a method which observes the patient's habitual movement patterns and teaches new patterns based on efficient active or passive repetitive conditioning. Additional techniques that may be useful for neuromuscular reeducation are Bobath concept, which promotes motor learning and efficient motor control, and biomechanical ankle platform system (BAPS) boards.

Physical therapy re-evaluation (typically 20 minutes) [HCPCS 97164]

Upon re-evaluation, the established care plan is reviewed and an interim history is taken requiring the use of standardized tests and measures. The patient's response to treatment is evaluated and the plan of care is revised based on the patient's measurable response.

Physical therapy techniques to 1 or more regions (each 15 minutes) [HCPCS 97140]

Manual therapies are skilled, specific, hands-on techniques usually performed by physical therapists, occupational therapists, chiropractors, osteopaths, and/or physiatrists to diagnose and treat soft tissue and joint problems. The goal of manual therapy is to modulate pain and induce relaxation, increase range of motion (ROM), facilitate movement, function, and stability, decrease inflammation, and improve muscle tone and extensibility. Tissue mobilization involves slow, controlled myofascial stretching using deep pressure to break up fibrous muscle tissue and/or connective tissue adhesions. Manipulation is a more forceful stretching of the myofascial tissue that takes the joint just beyond its restricted barrier. Manual lymphatic drainage is a type of light massage employed to reduce swelling by gentle movement of the skin in the direction of lymphatic flow. Manual traction involves the controlled counterforce of the therapist to induce asymptomatic strain by gently stretching muscle and/or connective tissue.

Amount and speed of breathed air measurement and graphic recording before and after medication administration [HCPCS 94060]

Spirometry with bronchodilation responsiveness is a pulmonary function test that is used to help diagnose the cause of shortness of breath and to monitor existing pulmonary disease, such as chronic bronchitis, emphysema, pulmonary fibrosis, chronic obstructive pulmonary disease (COPD), and asthma. The test is first performed without administration of a bronchodilator. A spirometry device consisting of a mouthpiece and tubing connected to a machine that records and displays results is used to perform the test. The patient inhales deeply and then exhales through the mouthpiece. Inhalation and exhalation measurements are first taken with the patient breathing normally. The patient is then instructed to perform rapid, forceful inhalation and exhalation. The spirometer records the volume of air inhaled, exhaled, and the length of time each breath takes. A bronchodilator medication is administered and the test is repeated. The test results are displayed on a graph that the physician reviews and interprets in a written report.

CPAP (continuous positive airway pressure) mask or breathing tube initiation and management for night time respiratory muscle rest [HCPCS 94660]

Continuous positive airway pressure (CPAP) ventilation is used primarily to treat sleep apnea. It may also be prescribed to treat preterm infants whose lungs have not fully developed. CPAP uses a mask or other breathing device that fits over the nose and mouth which is connected via a tube to a CPAP device. The CPAP machine delivers an air mixture at a continuous low level of pressure. The continuous positive airway pressure keeps the airways open and prevents mechanical obstruction of the flow of air caused by relaxation and collapse of airway structures during sleep. This code is used for initial set-up and management. A durable medical device provider delivers the CPAP device and other required equipment to the home or a residential facility. The device is set up and programmed to the settings indicated by the written prescription obtained from the physician or other qualified health care professional. The patient or caregiver is instructed on correct use of the CPAP and then is asked to demonstrate understanding by placing the mask over the mouth and nose and turning on the machine.

Routine EKG (electrocardiogram) tracing using at least 12 wires [HCPCS 93005]

An ECG is used to evaluate the electrical activity of the heart. The test is performed with the patient lying prone on the exam table. Small plastic patches are attached at specific locations on the chest, abdomen, arms, and/or legs. Leads (wires) from the ECG tracing device are then attached to the patches. A tracing is obtained of the electrical signals from the heart. Electrical activity begins in the sinoatrial node which generates an electrical stimulus at regular intervals, usually 60 to 100 times per minute. This stimulus travels through the conduction pathways to the sinoatrial node causing the atria to contract. The stimulus then travels along the bundle of His which divides into right and left pathways providing electrical stimulation of the ventricles causing them to contract. Each contraction of the ventricles represents one heart beat. The ECG tracing includes the following elements: P wave, QRS complex, ST segment, and T wave. The P wave, a small upward notch in the tracing, indicates electrical stimulation of the atria. This is followed by the QRS complex which indicates the ventricles are electrically stimulated to contract. The short flat ST segment follows and indicates the time between the end of the ventricular contraction and the T wave. The T wave represents the recovery period of the ventricles. The physician reviews, interprets, and provides a written report of the ECG recording taking care to note any abnormalities.

Airway inhalation treatment to relieve airway obstruction or for sputum collection (inhaled pressure or nonpressure treatment) [HCPCS 94640]

The patient is placed on intermittent inhalation treatment for acute airway obstruction or to induce sputum production for therapeutic and/or diagnostic purposes. To treat acute airway obstruction, pressurized or nonpressurized bronchodilator medication is delivered for short intervals several times a day using an inhaler, nebulizer, aerosol generator, or an intermittent positive pressure breathing (IPPB) device. Bronchodilator medication is suspended as fine particles within a gaseous propellant and taken into the lungs as a fine spray. The medication acts to relax the smooth muscle of the bronchioles and lung tissue, which has constricted in conditions such as an asthma attack or hypersensitivity reaction, severely restricting air flow. The patient uses the prescribed pressurized or nonpressurized inhalation device as directed by the physician typically for 10-15 minutes several times during the day. To induce sputum production for diagnostic purposes, an isotonic or hypertonic solution is delivered using a nebulizer or other device. These solutions induct secretion of sputum in the lower airways. The patient must cough to expectorate the secretions which are collected in a sterile container and sent to the laboratory for separately reportable analysis.

Blood or blood products transfusion [HCPCS 36430]

Blood and blood components include whole blood, platelets, packed red blood cells, and plasma products. Transfusions are performed to replace blood that is lost or depleted due to an injury, surgery, sickle cell disease, or treatment for a malignant neoplasm. Red blood cells are given to increase the number of blood cells that transport oxygen and nutrients throughout the body, platelets to control bleeding and improve blood clotting, and plasma to replace total blood volume and provide blood factors that improve blood clotting. The skin is prepped over the planned transfusion site and an intravenous line inserted. Any medication ordered by the physician is administered prior to the transfusion. The blood and/or blood components are administered. The patient is monitored during the transfusion for any signs of adverse reaction.

Breathing tube insertion into windpipe cartilage with endoscope (emergent) [HCPCS 31500]

The mouth is opened and any dentures are removed. A laryngoscope is passed into the hypopharynx and the glottis and vocal cords are visualized. A properly sized endotracheal tube is selected and the balloon is inflated. A stylet is inserted into the endotracheal tube and the tube and stylet are bent into a crescent shape. The endotracheal tube and stylet are inserted alongside the laryngoscope into the trachea and positioned with the balloon lying just beyond the vocal cords. The stylet is removed and the endotracheal tube is connected to the ventilation device and secured with tape. Breath sounds are checked using a stethoscope to ensure that the endotracheal tube is properly positioned.

Collection of blood specimen from arterial puncture for diagnosis [HCPCS 36600]

The radial artery is the most common site for arterial puncture with alternative sites being the axillary and femoral arteries. The arterial puncture site is selected. The skin is prepped for sterile entry. The selected artery is punctured and the necessary blood samples obtained for separately reportable laboratory studies. The needle is withdrawn and pressure applied to the puncture site.

Indwelling bladder catheter insertion (simple) [HCPCS 51702]

A temporary indwelling catheter is inserted into the bladder. This may be referred to as Foley catheterization. A catheter kit is prepared. The urethra is cleansed with antiseptic solution. A sterile Foley catheter is inserted through the urethra into the bladder. The balloon is then inflated with about 10 cc of water to keep it in place. The catheter is attached to a sterile drainage bag and urine is continuously drained from the bladder.

Needle insertion into vein for collection of blood sample [HCPCS 36415]

An appropriate vein is selected, usually one of the larger anecubital veins such as the median cubital, basilic, or cehalic veins. A tourniquet is placed above the planned puncture site. The site is disinfected with an alcohol pad. A needle is attached to a hub and the vein is punctured. A Vacuainer tube is attached to the hub and the blood specimen is collected. The Vacutainer tube is removed. Depending on the specific blood tests required, multiple Vacutainers may be filled from the same punchture site.

Skin and muscle removal (first 20 sq cm or less) [HCPCS 11043]

Skin and tissue removal (each additional 20 sq cm) [HCPCS 11045]

Skin and tissue removal (first 20 sq cm or less) [HCPCS 11042]

Abdominal ultrasound (limited) [HCPCS 76705]

A real time abdominal ultrasound is performed with image documentation. The patient is placed supine. Acoustic coupling gel is applied to the skin of the abdomen. The transducer is pressed firmly against the skin and swept back and forth over the abdomen and images obtained. The ultrasonic wave pulses directed at the abdomen are imaged by recording the ultrasound echoes. Any abnormalities are evaluated to identify characteristics that might provide a definitive diagnosis. The physician reviews the ultrasound images of the abdomen and provides a written interpretation.

Abdominal x-ray (2 views) [HCPCS 74019]

A radiologic examination of the abdomen images the internal organs, soft tissue (muscle, fat), and supporting skeleton. X-ray imaging uses indirect ionizing radiation to take pictures of non-uniform material, such as human tissue, because of its different density and composition, which allows some of the x-rays to be absorbed and some to pass through and be captured. This produces a 2D image of the structures. The radiographs may be taken to look for size, shape, and position of organs, pattern of air (bowel gas), obstruction, foreign objects, and calcification in the gallbladder, urinary tract, and aorta. A radiologic examination of the abdomen may be ordered to diagnose abdominal distention and pain, vomiting, diarrhea or constipation, and traumatic injury; it may also be obtained as a screening exam or scout film prior to other imagining procedures. Common views of the abdomen include front to back anteroposterior (AP) with the patient lying supine or standing erect, back to front posteroanterior (PA) with the patient lying prone, lateral with the patient lying on the side, lateral decubitus anteroposterior (side lying, front to back view), lateral dorsal decubitus (lying supine, side view), oblique (anterior or posterior rotation), and coned (small collimated) views which may be used to localize and differentiate lesions, calcifications, or herniations.

Abdominal x-ray (single view) [HCPCS 74018]

Ankle x-ray (2 views) [HCPCS 73600]

A radiologic examination of the ankle images the bones of the distal lower extremities including the tibia, fibula, and talus. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Ankle x-rays may also be used to determine whether there is satisfactory alignment of lower extremity bones following fracture treatment. Standard views of the ankle include front to back anteroposterior (AP), lateral (side), oblique (semi-prone position with body and leg partially rotated), and stress study with traction placed on the joint manually.

Ankle x-ray (minimum of 3 views) [HCPCS 73610]

Arm x-ray of forearm (2 views) [HCPCS 73090]

A radiologic examination of the forearm is done. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. Frontal views, or back to front (PA) views and lateral views are necessary to show the radius and ulna and assess the extent and direction of injury. Since the radius and ulna are anatomically connected at both ends of the bones with ligaments, the two bones function in a manner that makes the forearm considered as a single unit when assessing injury. The two standard views taken for x-ray examination of the forearm include the anteroposterior (AP) view, and the lateral view.

Arm x-ray of upper arm (minimum of 2 views) [HCPCS 73060]

A radiologic examination of the humerus is done with a minimum of 2 views taken. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The surgical neck of the humerus is the most common site of fracture. Shaft fractures are often associated with some kind of pathological lesion. X-rays of the humerus can be taken to detect deformities or lesions in the upper arm, such as cysts, tumors, late stage infection, or other diseases as well as a broken bone. The standard views of the humerus include the front to back anteroposterior view and the side, or lateral view.

Arteries and arterial grafts ultrasound of one arm (limited study) [HCPCS 93931]

Arteries and arterial grafts ultrasound of one leg (limited study) [HCPCS 93926]

A vascular ultrasound study is performed to evaluate the lower extremity arteries or arterial bypass grafts. A duplex scan uses both B-mode and Doppler studies. A clear gel is placed on the skin of the lower extremity over the region to be studied. A B-mode transducer is placed on the skin and real-time images of the arteries or arterial bypass grafts are obtained. A Doppler probe within the B-mode transducer provides information on the pattern and direction of blood flow in the artery. The B-mode transducer produces ultrasonic sound waves that move through the skin and bounce off the arteries when the probe is moved over the region being studied. The Doppler probe produces sound waves that bounce off blood cells moving within the artery. The reflected sound waves are sent to an amplifier that makes the sound waves audible. The pitch of the sound waves changes if there is reduced blood flow, or ceases altogether if a vessel is completely obstructed. A computer converts the sound waves to images that are overlaid with colors to produce video images showing the speed and direction of blood flow as well as any obstruction. Spectral Doppler analysis is performed to provide information on anatomy and hemodynamic function, including information on the presence of narrowing and plaque formation within the arteries. The physician reviews the duplex scan and provides a written interpretation of findings.

Blood flow (outside of the brain) ultrasound on both sides of head and neck [HCPCS 93880]

A vascular ultrasound study is performed to evaluate the extracranial arteries which include the common carotid and external carotid arteries. A duplex scan uses both B-mode and Doppler studies. A clear gel is placed on the skin over the arteries to be studied. A B-mode transducer is placed on the skin and real-time images of the artery are obtained. A Doppler probe within the B-mode transducer provides information on pattern and direction of blood flow in the artery. The B-mode transducer produces ultrasonic sound waves that move through the skin and bounce off the arteries when the probe is placed over the arteries at various locations and angles. The Doppler probe produces sound waves that bounce off blood cells moving within the artery. The reflected sound waves are sent to an amplifier that makes the sound waves audible. The pitch of the sound waves changes if there is reduced blood flow, or ceases altogether if a vessel is completely obstructed. A computer converts the sound waves to images that are overlaid with colors to produce video images showing the speed and direction of blood flow as well as any obstruction.

Chest x-ray (2 views) [HCPCS 71046]

A radiologic examination of the chest is performed. Chest radiographs (X-rays) provide images of the heart, lungs, bronchi, major blood vessels (aorta, vena cava, pulmonary vessels), and bones, (sternum, ribs, clavicle, scapula, spine). The most common views are frontal (also referred to as anteroposterior or AP), posteroanterior (PA), and lateral. To obtain a frontal view, the patient is positioned facing the x-ray machine. A PA view is obtained with the patient's back toward the x-ray machine. For a lateral view, the patient is positioned with side of the chest toward the machine. Other views that may be obtained include apical lordotic, oblique, and lateral decubitus. An apical lordotic image provides better visualization of the apical (top) regions of the lungs. The patient is positioned with the back arched so that the tops of the lungs can be x-rayed. Oblique views may be obtained to evaluate a pulmonary or mediastinal mass or opacity or to provide additional images of the heart and great vessels. There are four positions used for oblique views including right and left anterior oblique, and right and left posterior oblique. Anterior oblique views are obtained with the patient standing and the chest rotated 45 degrees. The arm closest to the x-ray cassette is flexed with the hand resting on the hip. The opposite arm is raised as high as possible. The part of the chest farthest away from the x-ray cassette is the area being studied. Posterior oblique views are typically obtained only when the patient is too ill to stand or lay prone for anterior oblique views. A lateral decubitus view is obtained with the patient lying on the side; the patient's head rests on one arm, and the other arm is raised over the head with the elbow bent. Images are recorded on hard copy film or stored electronically as digital images. The physician reviews the images, notes any abnormalities, and provides a written interpretation of the findings.

CTA scan of head blood vessels with contrast to examine blood clots or aneurysms [HCPCS 70496]

A computed tomographic angiography (CTA) of the head is performed with contrast material including image postprocessing. Noncontrast images may also be obtained and are included when performed. CTA provides images of the blood vessels using a combination of computed tomography (CT) and angiography with contrast material. When angiography is performed using CT, multiple images are obtained and processed on a computer to create detailed, two-dimensional, cross-sectional views of the blood vessels. These images are then displayed on a computer monitor. The patient is positioned on the CT table. An intravenous line is inserted into a blood vessel, usually in the arm or hand. Non-contrast images may be obtained. A small dose of contrast is injected and test images are obtained to verify correct positioning. The CTA is then performed. Contrast is injected at a controlled rate and the CT table moves through the CT machine as the scanning is performed. After completion of the CTA, the radiologist reviews and interprets the CTA images of the head.

CTA scan of neck blood vessels with contrast to examine blood clots or aneurysms [HCPCS 70498]

A computed tomographic angiography (CTA) of the neck is performed with contrast material including image postprocessing. Noncontrast images may also be obtained and are included when performed.

Elbow x-ray (2 views) [HCPCS 73070]

A radiologic examination of the elbow is done. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. X-rays of the elbow are usually considered necessary to assess for fractures or dislocations when the normal range of motion for extension, flexion, supination, and pronation cannot be carried out. Most acute disruptions of the elbow joint can be diagnosed by conventional x-ray examination, with the minimum number of views including the front to back anteroposterior projection with the elbow in as full extension as possible, and the side, or lateral image taken in flexion. A complete series of images also includes an oblique view of the radial head-capitellar image to help diagnose suspected subtle fractures involving the radial head or in cases of acute pain and trauma. The patient needs to be able to hold the elbow in full extension for the front view and in 90 degree flexion for the oblique and lateral views as much as possible.

Finger(s) x-ray (minimum of 2 views) [HCPCS 73140]

A radiologic examination of the finger(s) is done with at least 2 different projections taken. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, interphalangeal (IP) joint dislocations, deformities, degenerative bone conditions, osteomyelitis, arthritis, foreign body, or tumors. The posteroanterior projection is taken with the palm down flat, fingers extended, and slightly apart to show the metacarpals, phalanges, and IP joints of the target finger(s). Anteroposterior views are taken with the back of the hand placed on the film and the x-ray beam going from palmar to dorsal direction. Lateral views are taken with the ulnar side of the hand on the film cassette and the fingers spread apart to avoid overlap, sometimes supported from underneath. Oblique views can be obtained with the hand placed palm down and the radial side rotated 45 degrees up away from the surface, with the fingers extended and spread apart.

Foot x-ray (2 views) [HCPCS 73620]

A radiologic examination of the foot images the bones of the distal lower extremity and may include the tibia, fibula, talus, calcaneus, cuboid, navicular, cuneiform, metatarsals, and phalanges. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Foot x-rays may also be used to determine whether there is satisfactory alignment of foot bones following fracture treatment. Standard views of the foot include top to bottom dorsal planter (DP), lateral (side), oblique (semi-prone position with body and leg partially rotated), and stress study with traction placed on the joint manually.

Foot x-ray at heel of foot (minimum of 2 views) [HCPCS 73650]

A radiologic examination of the calcaneus images the bones of the distal lower extremity and usually includes the tibia, fibula, and talus. A radiologic examination of the toe(s) (phalanges) will usually include the metatarsals. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector.

The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Calcaneus and toe(s) x-rays may also be used to determine whether there is satisfactory alignment of lower extremity bones following fracture treatment. Standard views to image the calcaneus include lateral (side) and axial (supine with foot dorsiflexed). Common views to image the toe(s) include top to bottom dorsal planter (DP) and oblique (supine with leg rotated medially to image the 1st, 2nd, and 3rd digits and laterally to image the 4th and 5th digits).

Hand x-ray (2 views) [HCPCS 73120]

X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, dislocations, deformities, degenerative bone conditions, osteomyelitis, arthritis, foreign body, or tumors. Hand x-rays are also used to help determine the 'bone age' of children and assess whether any nutritional or metabolic disorders may be interfering with proper development. The posteroanterior projection is taken with the palm down flat and may show not only the metacarpals, phalanges, and interphalangeal joints, but the carpal bones, radius, and ulna as well. Lateral views may be taken with the hand placed upright, resting upon the ulnar side of the palm and little finger with the thumb on top, ideally with the fingers supported by a sponge and splayed to avoid overlap. Oblique views can be obtained with the hand placed palm down and rolled slightly to the outside with the fingertips still touching the film surface. The beam is angled perpendicular to the cassette for oblique projections and aimed at the middle finger metacarpophalangeal joint.

Head and neck ultrasound [HCPCS 76536]

An ultrasound examination of soft tissues of the head and neck is performed with image documentation. The thyroid, parathyroid, or parotid glands and surrounding soft tissue may be examined. Ultrasound visualizes the body internally using sound waves far above human perception bounce off interior anatomical structures. As the sound waves pass through different densities of tissue, they are reflected back to the receiving unit at varying speeds and converted into pictures displayed on screen. A linear scanner or mechanical sector scanner is used to evaluate the shape, size, border, internal architecture, distal enhancement, color flow, and echogenicity of the soft tissue structures of the head and neck as well as any lesions or masses. The echogenicity is compared to that of the surrounding muscle tissue. The physician reviews the images and provides a written interpretation.

Hip x-ray of both hips with pelvis (2 views) [HCPCS 73521]

A radiologic examination is done on both the left and the right hip, which may also include the pelvis. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, dislocations, deformities, degenerative bone conditions, osteomyelitis, arthritis, foreign body, infection, or tumor. Hip standard views that are taken most frequently include the front to back anteroposterior view taken with the patient lying supine and the legs straight, rotated slightly inward; the lateral ‘frog-leg’ view, taken with the hips flexed and abducted and the knees flexed with the soles of the feet placed together; a cross table view with the unaffected hip and knee flexed at a 90 degree angle out of the way and the beam aimed perpendicular to the long axis of the femur on the affected side. Another type of lateral view is taken with the hip flexed 45 degrees and abducted 45 degrees and the beam aimed perpendicular to the table. A front to back view of the hips in a pelvic view is often taken with the patient supine and both legs rotated slightly inward about 15 degrees.

Hip x-ray of hip with pelvis (2 to 3 views) [HCPCS 73502]

A radiologic examination of the hip is done on either the left or the right side, which may also include the pelvis. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, dislocations, deformities, degenerative bone conditions, osteomyelitis, arthritis, foreign body, infection, or tumor. Hip standard views that are taken most frequently include the front to back anteroposterior view taken with the patient lying supine and the legs straight, rotated slightly inward; the lateral ‘frog-leg’ view, taken with the hips flexed and abducted and the knees flexed with the soles of the feet placed together; a cross table view with the unaffected hip and knee flexed at a 90 degree angle out of the way and the beam aimed perpendicular to the long axis of the femur on the affected side. Another type of lateral view is taken with the hip flexed 45 degrees and abducted 45 degrees and the beam aimed perpendicular to the table.

Imaging of arm joint by MRI without contrast [HCPCS 73221]

Magnetic resonance imaging is done on a joint of the upper or lower arm. Magnetic resonance is a noninvasive, non-radiating imaging technique that uses the magnetic properties of hydrogen atoms in the body. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. The powerful magnetic field forces the hydrogen atoms to line up. Radiowaves are then transmitted within the strong magnetic field. Protons in the nuclei of different types of tissues emit a specific radiofrequency signal that bounces back to the computer, which processes the signals and converts the data into tomographic, 3D images with very high resolution. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. Small coils that help transmit and receive the radiowaves may be placed around the joint. MRI scans on joints of the upper extremity are often done for injury, trauma, unexplained pain, redness, or swelling, and freezing of a joint with loss of motion. MRI scans provide clear images of areas that may be difficult to see on CT.

Imaging of brain by MRI without contrast [HCPCS 70551]

Magnetic resonance imaging is done on the brain. MRI is a noninvasive, non-radiating imaging technique that uses the magnetic properties of hydrogen atoms in the body. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. The powerful magnetic field forces the hydrogen atoms to line up. Radiowaves are then transmitted within the strong magnetic field. Protons in the nuclei of different types of tissues emit a specific radiofrequency signal that bounces back to the computer, which processes the signals and converts the data into tomographic, 3D images with very high resolution. MRI of the brain provides reliable information for diagnosing the presence, location, and extent of tumors, cysts, or other masses; swelling and infection; vascular disorders or malformations, such as aneurysms and intracranial hemorrhage; disease of the pituitary gland; stroke; developmental and structural anomalies of the brain; hydrocephalus; and chronic conditions and diseases affecting the central nervous system such as headaches and multiple sclerosis.

Imaging of middle spinal canal by MRI without contrast [HCPCS 72146]

Magnetic resonance imaging (MRI) is done on the thoracic spinal canal and contents. MRI is a noninvasive, non-radiating imaging technique that uses the magnetic properties of nuclei within hydrogen atoms of the body. The powerful magnetic field forces the hydrogen atoms to line up. Radiowaves are then transmitted within the strong magnetic field. Protons in the nuclei of different types of tissues emit a specific radiofrequency signal that bounces back to the computer, which records the images. The computer processes the signals and converts the data into tomographic, 3D, sectional images in slices with very high resolution. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. MRI scans of the spine are often done when conservative treatment of back/neck pain is unsuccessful and more aggressive treatments are considered or following surgery.

Imaging of upper spinal canal by MRI without contrast [HCPCS 72141]

Joint or other non-blood vessel structure of arm or leg ultrasound (partial) [HCPCS 76882]

Ultrasound, also referred to as sonography and echography, is a non-invasive imaging technique that uses high-frequency sound waves to evaluate tissues and structures. Nonvascular structures of the extremities that may be evaluated by ultrasound include periarticular soft tissue masses, muscles, tendons, nerves, ligaments, and joints. Common conditions that can be detected or evaluated by ultrasound include cystic lesions, solid tumors, abscesses, joint effusion, tendon tears, tendonitis, tenosynovitis, nerve compression, and stress fractures. Acoustic coupling gel is applied to the extremity to be examined. An ultrasound probe is placed against the skin and moved over the target joint area to be examined as sound waves pass through and bounce off extremity tissues and structures. The sound waves are reflected back to the receiving unit at varying speeds and converted into images. Longitudinal, transverse, and oblique images are obtained. The physician reviews the images and provides a written interpretation.

Knee x-ray (1 or 2 views) [HCPCS 73560]

A radiologic examination of the knee images the femur, tibia, fibula, patella, and soft tissue. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Knee x-rays may also be used to determine whether there is satisfactory alignment of lower extremity bones following fracture treatment. Standard views of the knee include front to back anteroposterior (AP), lateral (side), and back to front posteroanterior (PA) with variations in the flexion of the joint, and weight bearing and non-weight bearing postures.

Leg ultrasound of arteries and arterial grafts of both legs (complete study) [HCPCS 93925]

A vascular ultrasound study is performed to evaluate the lower extremity arteries or arterial bypass grafts. A duplex scan uses both B-mode and Doppler studies. A clear gel is placed on the skin of the lower extremity over the region to be studied. A B-mode transducer is placed on the skin and real-time images of the arteries or arterial bypass grafts are obtained. A Doppler probe within the B-mode transducer provides information on the pattern and direction of blood flow in the artery. The B-mode transducer produces ultrasonic sound waves that move through the skin and bounce off the arteries when the probe is moved over the region being studied. The Doppler probe produces sound waves that bounce off blood cells moving within the artery. The reflected sound waves are sent to an amplifier that makes the sound waves audible. The pitch of the sound waves changes if there is reduced blood flow, or ceases altogether if a vessel is completely obstructed. A computer converts the sound waves to images that are overlaid with colors to produce video images showing the speed and direction of blood flow as well as any obstruction. Spectral Doppler analysis is performed to provide information on anatomy and hemodynamic function, including information on the presence of narrowing and plaque formation within the arteries. The physician reviews the duplex scan and provides a written interpretation of findings.

Lower leg x-ray (2 views) [HCPCS 73590]

A radiologic examination of the tibia and fibula images the bones of the distal lower extremities and may include the knee and ankle joints.

Standard views of the tibia and fibula include front to back anteroposterior (AP) and lateral (side).

Rib cage x-ray of ribs on one side of body (2 views) [HCPCS 71100]

Rib radiographs (x-rays) are typically obtained following trauma to the rib cage to determine if fractures or other internal injuries are present. The most common views of the ribs are anteroposterior (AP) (frontal) and oblique. There are four positions used for oblique views: right anterior oblique, left anterior oblique, right posterior oblique, and left posterior oblique. Anterior oblique views are obtained with the patient standing and the chest rotated 45 degrees. The arm closest to the x-ray cassette is flexed with the hand resting on the hip. The opposite arm is raised as high as possible. The part of the chest farthest away from the x-ray cassette is the area that is being studied. Posterior oblique views are typically obtained only when the patient is too ill to stand or lay prone for anterior oblique views.

Shoulder x-ray (single view) [HCPCS 73020]

A radiologic examination of the shoulder is done. The shoulder is the junction of the humeral head and the glenoid of the scapula. Standard views include the anteroposterior (AP) view and the lateral 'Y' view, named because of the Y shape formed by the scapula when looking at it from the side. An axial view can also be obtained for further assessment when the patient is able to hold the arm in abduction. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures.

Spinal x-ray of lower and sacral spine (2 or 3 views) [HCPCS 72100]

Wrist x-ray (2 views) [HCPCS 73100]

A radiologic examination of the wrist is done. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, dislocations, deformities, arthritis, foreign body, infection, or tumor. Wrist standard views include the front to back anteroposterior (AP) or back to front posteroanterior (PA) projection; the lateral view with the elbow flexed and the hand and wrist placed thumb up; and oblique views. Oblique views are obtained with the hand and wrist either supinated or pronated with the hand slightly flexed so the carpal target area lies flat, and then rotating the wrist 45 degrees externally or internally. A more specialized image may be obtained for assessing carpal tunnel. For the carpal tunnel view, the forearm is pronated with the palm down, and the wrist is hyperextended as far as possible by grasping the fingers with the opposite hand and gently hyperextending the joint until the metacarpals and fingers are in a near vertical position.

X-ray of sacrum and tailbone (minimum of 2 views) [HCPCS 72220]

A radiologic examination of the sacrum and coccyx is done with at least 2 views obtained. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. Routine views include an anteroposterior (AP) or posteroanterior (PA) view of the sacrum, an AP or PA view of the coccyx, and lateral sacrum/coccyx views. For the sacral view, the patient's pelvis needs to be positioned correctly so the sacrum and sacroiliac joints are symmetrical. Because the coccyx has a forward curvature in relation to the sacrum, it is not automatically visualized when taking an AP view of the sacrum, and so another positioning is done for the coccyx. For lateral views, the patient stands sideways with feet shoulder width apart and arms crossed at the shoulders. Lateral imaging shows the entire 5th lumbar vertebra, the sacrum, and the coccyx. Good sacrum and coccyx imaging requires patient preparation with an empty bladder, clean colon, and removal of clothing in favor of wearing a gown. This is due to the difficulty these obstructions can cause in achieving a good radiographic image. Shielding is done for males, but is not possible for female patients.
